pollingSourceOrganicpollution mainly comes fromdomestic sewage,industrial wastewater,agricultural wastewater,etc.,which contain a large amount oforganic substancessuch asprotein,fat,carbohydrates,etc.ImpactOrganic pollutioncan causeblack andodorous water bodies,deteriorate water quality,affect the survivalof aquatic organisms,and disruptthe ecological balance of
